如何从.cs文件调用.aspx方法 [英] How to call method of .aspx from .cs file

问题描述

先生您好，
我创建网页的原因是我在.aspx文件中使用了javascript.我需要执行以下操作.:

我有**"save" **按钮，但是在源代码中，我将Java脚本用于** save **按钮，在其中我声明了一个名为** OnClientClick ="javascript:validateTextTest()" **的函数，并在其中源代码的头我称为此函数validateTextTest().

以下是源代码中的保存按钮:

< asp:Button ID ="Save" runat ="server" onclick ="Save_Click" Text ="Save" OnClientClick ="javascript:validateTextTest()"
宽度="63px"/>

现在我需要的是我可以在**.cs文件**的保存按钮中调用函数** validateTextTest **()吗?因为有两到三个文本框，如果我在三个文本框中保留一个texbox，则不应将其插入DB.

因此，请告诉我如何在.cs文件中调用该函数.请为我提供帮助.
谢谢，
Pradeep

推荐答案

为button_click编写服务器端事件，在此事件中，将javascript称为

Write a server side event for the button_click, in this event call javascript as

string script = "<script language="'javascript'">validateTextTest();</script>";
                ScriptManager.RegisterStartupScript(Page, Page.GetType(), Guid.NewGuid().ToString(), script, false);

谢谢

如果您需要更复杂的回发行为，则可以包含一个包含值的隐藏项，该值包含所需的回发行为.

Hi,

If you need a more complicated post back behaviour you can include a hidden which contains a value which includes your desired post back behaviour.

<asp:hidden id="hdnAction" runat="Server" xmlns:asp="#unknown" />

更新您的javascript方法以分配操作并提交表单:

Update your javascript method to assign an action and submit the form:

function validateTextTest() {

   // validation code

   document.getElementById('hdnAction').value = 'MyAction';
   document.forms[0].submit();

}

然后在您的页面中加载:

Then in your page load:

protected void Page_Load(Object sender, EventArgs e)
{

  if(IsPostBack)
  {
    switch(hdnAction.Value)
    {
      case "MyAction":
        //do action code
        break;
    }
  }

}

然后，从按钮中删除服务器事件绑定:

You then remove the server event binding from your button:

<asp:button id="Save" runat="server" text="Save" onclientclick="javascript : validateTextTest()" xmlns:asp="#unknown">
Width="63px" /></asp:button>
